I'm using an Atmel microcontroller together with an LCD Display, a 16-button keyboard and some LEDs. I'm using a 5V wall adapter to power all this on my breadboard.
However, I'm not sure what kind of decoupling capacitors to use or their size. From what I've read, 0.1uF ceramic caps are the best for this job, but the store in my city only has very low capacity ceramic ones, with 10nF being the largest. They do have 0.1uF polyester ones though.
What is the best one in my case? Also, does voltage rating matter at all, because the ceramic ones are rated to a massive 500 V.
